I have been reading up on help for the mold and now white spots on my very large over 25 year old jade plant. One suggestion was to spray it with a baking soda and vinegar solution, but I cannot find anywhere what the ratio is or if water is mixed with it. Could someone please help me with the recipe? I am in southwest Ontario and I do keep my plant outdoors all summer. I am wondering if it has been too humid for my plant? Mind you I do have 2 jade plants and so far the other has not been affected.
White Spots and Mold on Jade Plant

From the image it appears to be water spotting on the Jade Plant. Watering from above should be avoided.
I would also make sure that it is protected from rainfall, excess moisture can lead to root rot.
Mealybugs can be common on Jade Plants, but I don't see these on your plant.
Powdery Mildew is also possible, and is caused by a fungus. Improving air circulation can help.
